dc.description.abstractNewly designed frequency filter of the second order with the possibility of mutually independentcontrol of the pole frequency and quality factor is presented in this paper. Balanced-outputtransconductance amplifier (BOTA) and digitally adjustable current amplifier (DACA) are used asactive elements in this proposal. The pole frequency and quality factor can be tuned by the adjustablecurrent gain of three DACAs that are available in form of integrated circuit. The individual outputresponses of proposed frequency filter are verified using PSpice simulations and by experimentalmeasurement in laboratory.en
